Adhesiveless Bonding of Wood – A Review with a Focus on Wood Welding [PDF]
BioResources, 2021 Most industrially used synthetic wood adhesives release formaldehyde, which is carcinogenic for humans. Adhesiveless bonding of wood can be achieved using heat treatment by either hot-pressing method, suitable mainly for wood particles and fibres or by ...

Parameters of wood welding: A study with infrared thermography [PDF]
Holzforschung, 2006 Abstract Welding of wood is a well-known joining procedure that offers several advantages over traditional mechanical fasteners or gluing. During welding, extensive solid-state transformation phases occur in the so-called melting zone and the heat-affected zone. The nature and the extension of such transformations are correlated to the energy input and

The Influence of Different Wood Modifications on Pull-out Force of Rotary Welded Dowels
Drvna Industrija, 2023 The increasing use of modified wood justifies the intention to use it in joints made by rotary welding with dowels. Thermal modification, for example, increases the dimensional stability of wood by reducing its hygroscopicity and water absorption, but it
